Definitions

  • the present invention generally relates to a spiral distributor, and more particularly to an anti-separation spiral distributor and a paver having the separation-proof spiral distributor.
  • BACKGROUND OF THE INVENTION With the continuous improvement of road construction technology and the continuous improvement of road quality requirements, the application and status of asphalt concrete pavers have been paid more and more attention. The segregation phenomenon of asphalt concrete pavers on the road during construction is also Gaining importance. There are many reasons for the road surface segregation.
  • the road surface segregation caused by the asphalt concrete paver mainly includes hopper separation, spiral agitation separation, tamping and smelting, screed paving and segregation, and random segregation.
  • the squeegee is a translating layered conveying device that does not re-mix and mix the mixture, so the physical and temperature segregation of the mixture produced in the previous processes cannot be improved. For this reason, in recent years, attempts have been made to add a mixer truck in front of the paver, and the temperature and physical segregation are effectively improved by the functions of heat preservation, heating, and stirring. For the paver itself, improved segregation is achieved primarily through the structural design of the auger and the kinematic parameters.
  • the screw feeder will also stir the asphalt mixture twice during the conveying process.
  • the effect of the second mixing will be affected by the internal friction of the asphalt mixture and the mixture and the spiral.
  • the effect of the external friction between the reasonable, and the reasonable spreader screw feeder should be able to stir the mixture well, so that the mixture produced in the previous process can be effectively improved, while meeting the required mixing of different parts of the paving width.
  • the amount of material is used to ensure the flatness. This is the ultimate requirement for the design of the screw feeder and a reasonable way to improve the performance of the paver.
  • the spiral distributor drives the bottom of the sprocket box to easily produce longitudinal separation, that is, the strip-shaped separation belt along the driving direction appearing on the paving layer. This is due to the spatial interference of the spiral drive sprocket box, so that the left and right spirals are disconnected at a certain distance from the middle seam. The mixture at this break is not evenly spread and stirred by the screw, and will be at the bottom of the spiral drive sprocket box. Generate Stacking and squeezing, and relying only on the natural flow of the mixture to fill, the paving density is low and the gradation is uneven, forming a distinct strip-shaped segregation zone.
  • the problem to be solved by the present invention is to provide a screw feeder for a paver that can prevent segregation at the bottom of a drive sprocket of a screw feeder.
  • the present invention provides an anti-separation spiral distributor, which is disposed on a paver, including a left and right spiral and a spiral drive sprocket box, wherein the spiral drive sprocket box is provided with a front for entering
  • the mixture in the anti-separation spiral distributor is divided into plow-shaped dispensing devices on both sides.
  • left and right spirals on both sides of the spiral drive sprocket case are respectively fixedly provided with left reverse blades and right reverse blades for returning a part of the mixture to the bottom of the spiral drive sprocket case.
  • the plow-shaped dispensing device is connected with a steel plate, the steel plate is provided with a plurality of waist-shaped through holes, and the plow-shaped dispensing device is fixed by the bolt passing through the waist-shaped through holes. Screw drive on the sprocket box.
  • the present invention also provides a paver having the above-described anti-separation spiral distributor.
  • the anti-separation spiral distributor and paver of the invention have the following beneficial effects as follows:
  • the plow-shaped distribution device can effectively adjust the flow of the mixture, so that the asphalt mixture can be effectively stirred, and the mixture is reduced in the spiral.
  • the accumulation and extrusion at the bottom of the drive sprocket box reduces the longitudinal separation of the asphalt mixture and improves the paving quality of the road surface after paving.
  • FIG. 1 is a front view of an anti-separation spiral distributor of the present invention
  • Figure 2 is a left side view of the anti-separation spiral distributor of the present invention.
  • Figure 3 is a front elevational view of the plow-shaped dispensing device of the anti-separation spiral distributor of the present invention
  • Figure 4 is a right side view of the plow-shaped dispensing device of the anti-separation spiral distributor of the present invention
  • the plow-shaped dispensing device 1 of the anti-separation spiral distributor of the present invention has a shape resembling a nose shape, and the front central portion thereof is a plow beam 10, a steel plate 9 and a plow-shaped dispensing device. 1 is connected, and a plurality of through holes are formed in the steel plate 9. As shown in Fig. 5, in the top view of the plow-type dispensing device 1, it is substantially inverted triangle.
  • the plow-shaped dispensing device 1 is disposed in front of the spiral drive sprocket case 8, as shown in Fig. 1, in a preferred embodiment of the invention, the plow-shaped dispensing device 1 passes through the steel plate 9.
  • the through hole bolt 6 is fixed on and in front of the spiral drive sprocket case 8 of the anti-separation spiral distributor, wherein the through hole of the steel plate 9 through which the bolt 6 is passed is preferably a waist-shaped through hole, so that the bolt 6 can be The waist-shaped through hole slides up and down, so that the plow-shaped dispensing device 1 can be adjusted up and down according to working conditions.
  • the plow-shaped dispensing device 1 can also be directly welded to the steel structure of the screw drive sprocket case 8 by moving the lift cylinder 7 and the screw drive sprocket 8 up and down.
  • the asphalt mixture enters the anti-separation screw feeder from the feeder (not shown) in the direction of the paver frame 13 through the plow-shaped material.
  • the plough beam 10 of the apparatus 1 is divided into two sides of the plow-type dispensing device 1, and after being sent to the left baffle plate 4 and the right baffle plate 5, the left spiral blade 11 and the right spiral blade 12 on the left and right spirals
  • the rotation is carried to both sides of the trough formed by the left baffle 4, the right baffle 5, and the screed 14, so that the paving operation can be smoothly performed.
  • the plough beam 10 of the ploughing device 1 has a smooth arc transition on both sides of the device, which can reduce the flow resistance of the mixture, and is beneficial to the flow of the mixture, so that the mixture follows the plough beam on both sides of the ploughing device Spread evenly, thus avoiding the forced mixing of the mixture at the bottom of the sprocket box by the sprocket.
  • the left reverse spiral blade 2 and the right reverse spiral blade 3 installed on the left and right spirals on both sides of the spiral drive sprocket box 8 can reversely mix the asphalt mixture, and divide the plow-shaped dispensing device 1 into two.
  • the side mixture is returned to the bottom of the spiral drive sprocket box 8 while being thoroughly agitated, thereby preventing the asphalt mixture from being interrupted by the plow-type dispensing device 1 and breaking a certain distance from the slit.
  • the paver having the anti-separation spiral distributor of the present invention has a low density and uneven gradation of the mixture when the asphalt mixture passes through the plow-shaped distribution device at the screw drive sprocket 8
  • the phenomenon can effectively reduce the longitudinal segregation of the asphalt mixture at the screw drive sprocket box 8.
